Use of index analysis to evaluate the water quality of a stream receiving industrial effluents
Raphael Abrahão,Monica Carvalho,WR da Silva,Thaisa Orona Machado,Carmem Lúcia Moreira Gadelha,M Hernandez +5 more
TL;DR: In this article, the water quality of a stream that receives industrial effluents is evaluated through the analysis of two water quality indices: WQIOBJ and Bascaron Adapted Water Quality Index (WQIBA).
Journal ArticleDOI
Nitrate contamination and its relationship with flood irrigation management
TL;DR: In this paper, the authors analyze the evolution of nitrate contamination in relation to agronomic and management changes within a traditionally irrigated land, and show that although changes in crop pattern caused a 33% reduction in the nitrogen required through fertilization, the fertilization rates applied are still double the necessities.
Journal ArticleDOI
Impact of irrigation implementation on hydrology and water quality in a small agricultural basin in Spain
TL;DR: In this article, the effects of irrigation on a gully after it was implemented in its hydrological basin (7.38 km2) were assessed. And the results showed the correlation of irrigation with flow and the load of salts and nitrates exported, although no significant relationship with precipitation was detected.
Journal ArticleDOI
Simulating the transition of a semi-arid rainfed catchment towards irrigation agriculture
TL;DR: In this paper, the effects of land-use change in the semi-arid Lerma basin (Ebro valley, Spain), which underwent a transition from rainfed towards irrigation agriculture, were investigated.
Journal ArticleDOI
Impact of Climate Change on Mediterranean Irrigation Demand: Historical Dynamics of Climate and Future Projections
TL;DR: In this article, the authors proposed the climatic characterization of a historical series (1971-2000) and its future projections (2011-2099) for an Irrigation District located in the Middle Ebro Valley (Spain), for three different scenarios: low, medium, and high global emission levels of greenhouse gases.
